Summary:The invention belongs to the field of wireless sensor networks, and relates to a node optimal deployment method suitable for a wireless positionable sensor network. The method aims at processing optimal deployment of wireless positionable sensor network nodes, and comprises the following steps: acquiring a sensor node antenna gain estimation model in a discrete state; constructing a double-dipoleantenna radiation gain model and a field intensity estimation model in a simultaneous state; obtaining an optimization objective function through communication among a mobile charger, a sensing node and a common node; and optimizing a target function by adopting a multitask evolutionary algorithm based on an information positive migration mechanism to obtain an optimal deployment mode of the sensing nodes. The method has the characteristics that the energy utilization rate of the charger is effectively improved, the charging inactivation time is shortened, and meanwhile, the requirements of high-precision positioning
